ORGANIC-INORGANIC COMPLEX, AND COMPOSITION FOR FORMING SAME (As Amended)

An organic-inorganic complex-forming composition comprising:

• a) at least one organic silicon compound represented by formula (I):
• RnSiX4-n (I)
• (wherein R represents an organic group having a carbon atom directly bonded to Si, and X represents a hydroxyl group or a hydrolyzable group;
• and n represents 1 or 2, wherein when n is 2, each R is the same or different, and when (4−n) is 2 or more, each X is the same or different) and wherein a molar ratio of an organic silicon compound in which a solubility parameter of R(SP1) obtained by a Fedors' estimation method is smaller than a solubility parameter of an electromagnetic ray-curable compound (SP2) obtained by the Fedors' estimation method and a difference between the SP1 and the SP2 is 2.0 or more (Si1) to an organic silicon compound in which SP1 is smaller than SP2 and a difference between the SP1 and the SP2 is less than 2.0 or an organic silicon compound in which SP1 is larger than SP2 (Si2) (Si1:Si2) is within the range of 8:2 to 10:0, and/or a condensate of the organic silicon compound;
• b) an electromagnetic ray-curable compound;
• and
• c) metal compound particles.
